Why Tire Size Matters

Your car’s tires play a critical role in both safety and performance. The size of the tires affects how your car handles, how it accelerates and brakes, and how it handles corners. Tires that are too big or too small can negatively impact your car’s performance in these areas. Additionally, the wrong tire size can affect your speedometer and odometer readings.
